The 2015+ Subaru STI Mishimoto Coolant Expansion Tank adds some additional reliability and engine bay styling to your Subaru. Stock plastic coolant expansion tanks are prone to failure after years of constant temperature variations. The Mishimoto tank is constructed from durable, TIG-welded aluminum with barbed fittings for optimal durability and longevity. This expansion tank provides a 50% increase in capacity compared to the stock unit and features a polished silver or anodized black finish that will look great in your engine bay. As with all Mishimoto products, this expansion tank includes the Mishimoto Lifetime Warranty and everything you need for an easy install.
